Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for motion sickness prevention require additional user training and do not naturally and readily enable users to overcome sensory mismatches leading to adverse effects.
Innovation Solution
A sensory compensation device that includes a position and orientation sensor to generate data, an optical sensor to capture real-time images, and a processor to adjust images in relation to detected orientations and accelerations, providing compensated images to align visual perception with vestibular sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual orientation cues are provided to reflect motion (as in the '680 patent), then motion sickness is compensated, but additional user training and user experience are required
Solution Approach 1:
The system automatically detects user motion through inertial sensors and dynamically adjusts the displayed visual content to compensate for sensory mismatch without requiring any user training or manual intervention. The device serves itself by autonomously calculating and applying the necessary visual corrections based on real-time acceleration and orientation data
Solution Approach 2:
The system implements a closed-loop feedback mechanism where inertial sensors continuously monitor user motion, the processor calculates the sensory mismatch in real-time, and the display automatically adjusts visual content to counteract the detected motion, creating a continuous self-correcting cycle that eliminates the need for user training
2Reliability
If visual cues are displayed to alleviate sensory mismatch, then motion sickness effects are reduced, but the device complexity increases
Solution Approach 1:
The system combines inertial motion detection, real-time image capture, image processing, and visual display adjustment into a single integrated device. The inertial sensor, image capture device, and display are merged into one unit that automatically processes and compensates for sensory mismatch without requiring separate external equipment
Solution Approach 2:
The display serves multiple functions: it displays the captured image content while simultaneously providing motion compensation by adjusting the visual content based on inertial sensor data. The same display hardware is used both for showing the camera feed and for delivering the sensory mismatch correction, eliminating the need for separate specialized display systems

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively alleviates motion sickness by ensuring that visual cues match the user's perceived motion, reducing sensory mismatch and its adverse effects.
